klipsch kda-500 amplifier suitable power supply capacitor replacement ?

by r2digital

I have a klipsch kda-500 that would turn on and allow me to get into the web management but it was picking up a lot of noise from audio sources so i decided to replace the smd caps on the power supply along with radial one. Some one was in here before me and they basically burned the bottom side of the traces off for the radial cap but i was able to repair it without any real problem. I thought i did a good job sourcing out replacement caps but apparently not and now i can't get the power supply to turn on it just constantly try's to keep turning on. Attached is a picture of the power supply before...

Lenovo V14-IILWont Only post with OnBoard RAM

by Kambi13

Hi all, need some help, I've got a Lenovo V14-IIL that as total of 8GB of RAM (4GB onBoard - 4GB Sloted), out of the blue it stopped posting, After investigating, found out that removing the RAM stick from the slot, the laptop would post and work with no other issues. So tried with a different RAM stick suspecting that the original one somehow died, but to my frustration the issue remained, so again tried a different number of known working RAM sticks with different capacities and speeds but with no avail.... Unplugged Battery, removed CMOS battery,Reset and Updated Bios, also measured voltages...

MTC Mtc4k58s21 58" TV Hk.T.Rt2851P838

by Bholu

Hello friends, I have MTC 58' TV which has stand by position. I thought the software was corrupt. I have downloaded the software from the internet but the data is not matching. The format window is opening from the TV software but none of the buttons on the remote or TV are working. Why? Can I edit this software with a hex editor? Is there any guide to edit this? Or does anyone have access to this software? Thank you very much for your help.

TDK ZWS150BAF-12

by Keshenatech1

Does anyone have a schematic or parts list for a ZWS150BAF-12 12V power supply? I have a dead one and I've determined the surface mount diode on the back side of the board that connects from the center leg of Q3 to the + side of the 420V 60uf capacitors has a 3.5 ohm short. I'm not having much luck trying to identify the diode as the part number is not very legible. In the attached picture, it's the black rectangular diode in the center. There are some numbers on it but I can't even tell if it's right side up or upside down. The picture is from a 2nd good working unit which is more legible...

Wharfedale Movie Star 70+ Schematic Required.

by hemant_2222

Hello Friends,

Greetings!

I have taken this active subwoofer from Wharfedale for restoration. This is already in a bad shape as far as the connections goes. It has already been worked by local technicians. The most important part that I am looking forward is the schematic diagram, as there is jumper placed and a track has been cut, as if to bypass the actual connection. I am not sure if this is by design or someone has tried something to achieve.

Another thing is the TDA7294 was badly treated with its legs cut and it had a crack too, so I have replaced it...

Assistance with identifying replacement caps on ASUS P5VDZ-MX

by crosswinds

Hello,

So, pulled a motherboard out from storage, was working when put away, wont post when I took it out of storage today.
Since it was working, and it looks to be essentially time that killed it I figured its a good idea to replace the caps before digging further.
Looks to be only good quality caps on this board, so might not be the issue. But it is closing in on 20 years now so, wont hurt i guess

Its a ASUS P5VDZ-MX board.

I would really appreciate some assistance on what the best replacement caps would be for these:

There was no ssd inside I placed the new ssd and tried to start the laptop but the only thing I get when I start up is a black screen and the keyboard is lighted up and changes the colors.

It's now looking like I bought a brick and got scammed.. can anybody help me out with this problem please?[/INDENT]

Help me find the short circuit on this WORKING Nvidia GTX1650

by aaronkatrini

Hi all,

Recently picked up this GTX1650 at a local flea market for a low price and wanted to use it on my secondary PC. I first tested the card and saw the fan spin for a split second and then nothing. Immediately I thought of a short circuit. Disassembled and found a shorted SMD capacitor, injected voltage into it (1V/4A) and two Mosfets got hot immediately (QN3103 & QN3107). Desoldered these Mosfets and the card turned back to life.

Bought replacements from Aliexpress and replaced them afterwards. Tried the card but still the saw the fan spin for a split second...

Samsung/UN65H6300AF LOGO APPEARS AND SHUTS OFF

by Super360

Hi as you can see from title, I have a samsung tv here that will show the smart tv logo and then no picture after that even hitting input or menu on remote and shows nothing but the backlight still appears to be on. The tv will turn itself off after a minute or so automatically. I'm somewhat confused if this is either a eeprom problem or a bad led strip problem. The power supply makes a pretty noticeable humming sound when it's turned on leading me to believe one of the leds are shorted but idk honestly. Any of you guys have any help for me? I have a good multi meter and can take pictures of whatever...
